    Default Tube bender question

    Hello everyone!I'm new here.
    Maybe I'm kicking a dead horse by asking about tube benders, but I've searched the forum and can't seem to find my answer. I was wondering what would be the best radius die to purchase for handlebars/frames and such. I was thinking a 180 degree 3" would work fine, but would like to hear some input before dropping the cash on a die that might not work.

    "...This tech article features a Mittler Brother Rotary Draw hydraulic bender. I have used and owned many different rotary draw benders over the years and they all have their pros and cons. I will caution everyone to stay away from cheap pipe benders that simply press a die into the tubing which causes the walls of the tubing to deform and can seriously reduce the strength of the finished product....

    For this set of bars I use a 3” radius die for all 4 bends...

    We got this one.. Haven't tested it yet, but it takes Woodward FAB and JD Tools dies.

    Looks like it will work fine.

    As far as the radius goes, we used a large compass and sketched out what we wanted to do with it. It really helps you visualize things when otherwise you're just left guessing.

    A while back I contacted flyweight. D they use 3 or 3.5" on their 1" sporty frames. I use a 3 for 1". Look up ctnewman and his tutorial for custom wooden does. I've seen handlebars made with as low as 2" dies. All numbers for the clr( centerline radius)
